2)

 

Check status of the POWER indicator lamp (LED) of the LX3V-4DA. 

On: The extension cable is properly connected. 

Off or flash: Check connection of extension cable. Also check the 5 V power supply capacity. 

3)

 

Check status of the 24 V power indicator lamps (LED) of the LX3V-4DA. 

On: 24 VDC is supplied. 

Off: Supply 24 VDC (+10%) to the LX3V-4DA.• 

4)

 

Check the status of the D/A conversion indicator lamp (LED) of the LX3V-4DA. 
Flash: D/A conversion are normal. 
On  or  off:  The  ambient  conditions  are  not  suitable  for  the  LX3V-4DA,  or  the  LX3V-4DA  is 
defective.• 

5)

 

Check  that  the  external  load  resistance  connected  to  each  analog  output  terminal  does  not 

exceed the capacity of the LX3V-4DA drive (voltage output: 2kΩ to 1 MΩ / current output: 500Ω).‘ 

6)

 

Check  the  output  voltage  or  current  value  using  a  voltmeter  or  ammeter,  and  confirm  that  the 
output  meets  the  I/O  characteristics.  If the  output  does  not  meet the  I/O  characteristics,  adjust 
the offset and gain again. Refer to section 8. 

 

To test the withstand voltage of the LX3V-4DA, connect all the terminals to the grounding terminal.
